Let’s talk about rocks

See this specific code 
```{r}
#| eval: false
print(rock)
```
Look at me!

And now about anxiety and other stuff

'data.frame':   300 obs. of  4 variables:
 $ anxiety    : num  50.2 31.5 34 37.1 48.3 ...
 $ flexibility: num  44.4 47.7 65.6 50.7 51.3 ...
 $ mindfulness: chr  "no" "yes" "no" "no" ...
 $ activity   : chr  "pilates" "altro" "pilates" "altro" ...
Look at me!

Figura 1 illustrates a baby wearing a nirs cap with frontal probes.

look how I’ve imported this nice pic! ;)

Figura 2 illustrates a plot

look how we directly plotted in Quarto (of course I copied Ottavia’s code) 
ggplot(mtcars, aes(hp, mpg, color = factor(am))) +
  geom_point() +
  geom_smooth(formula = y ~ x, method = "loess") +
  theme(legend.position = 'bottom')

Tabella 1 show the summary of the ChickWeight dataset

Tabella 1: ChickWeight data summary
Lista 1: Code use to generate the previous table 
kable(summary(ChickWeight)) %>%
  scroll_box(height = "200px", width = "100%")

If you write “#| eval: false” in the previous code ref, quarto won’t return a table twice
